So the increase in spacing is just a basic Velocity Formula, right? In truth I'm sure the Graph Editor will handle the bulk, but knowing the equation could help if I need to brute force a problem, or figure it out on paper.
I like your thinking, although I doubt you would find it easier to figure out on paper. I know I don't find it easier!
Here's the equation...(sqrt(h*g/2)*2)*((frame/fps)%((sqrt(h*g/2)*2)*2/g)) - (g*((frame/fps)%((sqrt(h*g/2)*2)*2/g))**2)/2Where:
v = velocity at the ground
g = acceleration of gravity
t = (frame/fps)%(v*2/g)
fps = scene's frame rate
frame = current frame
That will get the graph editor to do the bulk of the work, but then the only way to tweak it would be to edit your variables (like gravity).
But you often are working in a scene that doesn't have real world scale plus you wouldn't be able to stylise your timing and spacing to make it better than real life.
You might want to emphasise the weight or the hangtime for a different effect.
So in summary, it's much much easier to control your timing and spacing ;)
